Content

Just like most software, Breath of the Wild requires non-executable content files to work correctly. They are stored in the title content directory on Wii U and in the romfs on Switch.

To minimise loading times, files that are frequently loaded together or at the same time are packed into SARC archives. Because of this optimisation, a significant amount of game files are located within archives. Some files may also be present in more than a single archive with the same canonical resource name.
